Happened to me last Tuesday night too, after I booked my itin but the purchase didn't go through (don't know why, the credit card was fine).

When I called web support, I indicated (before the agent picked up) that I would complete the survey. At the conclusion of the call, I was surprised that the phone agent wanted to me to rate the call. I said I would wait for the automated survey to commence, then he asked again. And I said the same thing, and he asked again. So I said, "forget it".

Maybe UA thinks the rating would be higher if given in person vs. the automated system.
